Cambodia’s civilization has been profoundly shaped by Hinduism. Although the country is predominantly Buddhist today, Hinduism played a vital role in early Cambodian history, especially during the Khmer Empire (9th–15th centuries) . In fact, even as a small minority religion now, Hinduism’s legacy permeates Khmer culture, history, and art . This report provides a comprehensive overview of Hinduism’s influence on Khmer culture, covering historical development, mythology, religious practices, art and architecture, language, social customs, literature, and political systems. It especially highlights the Angkor period, when Hindu ideas and motifs reached their zenith in Cambodia, and examines how these influences continue into modern times.
Historical Development: Indian Influence and the Angkor Era
Hinduism first spread into Cambodia around the 1st–5th centuries CE via trade and cultural exchange with Indian traders, Brahmins, and scholars . The early Khmer kingdoms of Funan and Chenla (1st–8th centuries) absorbed Indian cultural elements – from Sanskrit language and Brahmi-derived scripts to Hindu religious ideologies used to legitimize kingship . For example, Chinese records recount an Indian Brahmin, Kaundinya, marrying a local Naga princess and founding the Funan dynasty, reflecting the blending of Indian and indigenous traditions in the kingdom’s origin (see Mythology section). By the 6th–8th centuries, ruling elites were patronizing Hindu cults, and Sanskrit terms like “Kambujadesha” (land of Kambuja) appear in inscriptions to designate the Khmer realm .
The Khmer Empire was founded in 802 CE when King Jayavarman II proclaimed himself a chakravartin (universal monarch) and devarāja (god-king) in a Hindu ritual on Phnom Kulen . This established Hinduism – particularly the worship of Shiva under the devarāja cult – as the state religion and ideological basis of kingship. Over the next centuries (9th–12th centuries), Khmer kings built countless Hindu temples and linga shrines across their realm . Sanskrit was the sacred language of court and liturgy during this peak era . The empire reached its apogee in the Angkor period, producing architectural marvels like Angkor Wat (dedicated to Vishnu) and numerous temples to Shiva, Vishnu, and other deities. While Buddhism also grew in parallel, Hinduism dominated officially until the 13th/14th century . By the late 12th century, rulers like Jayavarman VII adopted Mahayana Buddhism, and Theravada Buddhism gradually became dominant after the 14th century, leading to a decline of Hindu state patronage . Nevertheless, Hindu influence never disappeared – it lived on through syncretic practices, language, art, and rituals that persisted into modern Cambodian culture.
Mythology and Epic Literature in Khmer Culture
Hindu mythology became deeply ingrained in Khmer cultural narratives, blending with local legends to explain the origins of the land and kingship. A prime example is the foundation legend of Preah Thong and Neang Neak – the Khmer version of the Brahmin Kaundinya (Preah Thong) and the serpent princess Soma (Neang Neak). According to this myth, an Indian prince married a Naga princess and founded the first Cambodian kingdom . This tale symbolizes the merging of Hinduism with indigenous animist beliefs, as the Brahmin brought Indian religion and statecraft while the Naga lineage represents local water spirits and fertility cults . The union of Preah Thong and Neang Neak is said to have given rise to the Khmer people and their monarchs . To this day, the legend is celebrated in Cambodian wedding ceremonies – for instance, the groom holding the bride’s scarf (the “Neang Neak” sash) reenacts the Naga princess leading her husband, a custom traced back to this Hindu-origin myth .
Another pillar of Khmer mythology is the Ramayana epic, known in Cambodia as the Reamker (“Glory of Rama”). The Ramayana arrived in Southeast Asia with Hinduism, and by the Angkor period it had been adopted and localized as a central cultural story . The Reamker is Cambodia’s national epic poem, combining the Sanskrit Ramayana’s Hindu moral themes with Buddhist elements and Khmer folk nuances . It has been transmitted through oral tradition and later written texts (surviving manuscripts date from the 16th century) . Scenes from the Ramayana were carved into Angkorian temple walls nearly a millennium ago and have been retold in Khmer dance, theater, and literature ever since . In fact, the Ramayana (Reamker) permeates all forms of Cambodian art – from the bas-reliefs of Angkor Wat and Banteay Srei to paintings in the Royal Palace and the repertoire of the Royal Ballet . Similarly, episodes from the Mahabharata (such as the Battle of Kurukshetra) were depicted in temple carvings and likely known through courtly tradition . Khmer inscriptions and chronicles show that ancient Cambodians revered Hindu sages and heroes; for example, kings were eulogized by comparing their feats to those of Rama in battle, equating the king’s enemies to Ravana . One scholar noted that the Rāmāyana “perhaps more than anything else” helped weave together Khmer religious, ethical, and political life . In essence, Indian epic mythology provided Khmer civilization with a rich store of allegories and divine models that were integrated into local beliefs and state ideology.
Religious Beliefs and Practices: Syncretism and Worship
During the Angkorian era, Hinduism was the state religion and guided both public ritual and private devotion. The Khmer embraced the Hindu pantheon of gods – especially Shiva and Vishnu, and to a lesser extent Brahma and various Devi (goddesses) and demigods. Kings and temples tended to favor either Shaivism or Vaishnavism depending on royal preference. Early Angkor kings (9th–10th c.) venerated Shiva as supreme god (often in the form of the linga, a phallic symbol of Shiva’s cosmic essence), while the 12th-century King Suryavarman II built Angkor Wat as a grand temple dedicated to Vishnu . Throughout the empire, Brahmin priests conducted elaborate rituals at state temples, offering prayers in Sanskrit and performing Vedic fire ceremonies and lustration rites to honor the gods and sanctify the king’s rule . Temples were not only places of worship but also cosmic power centers – Angkorian temple architecture consciously recreated the Hindu cosmos, with temple-mountains representing Mount Meru, the abode of gods . For example, Angkor Wat’s concentric enclosures and its five towering spires are designed as a symbolic model of Mount Meru’s peaks, surrounded by the cosmic ocean (the moat) . Worshippers would ascend towards the central sanctuary (the summit of Meru) where the deity’s image or linga resided, reenacting a spiritual journey toward the divine.
Importantly, Hindu practice in Cambodia coexisted and merged with local beliefs and later Buddhist traditions, creating a unique syncretism. Indigenous Khmer animism – the worship of ancestor spirits, nature deities, and the naga serpent spirits of water – was never eradicated but was incorporated into state religion . The naga, for instance, became a potent symbol in Khmer Hindu iconography (multi-headed naga statues guard many temple causeways) and retained its role as protector of the land and bringer of rains. Similarly, apsaras (celestial nymphs in Hindu lore) were linked to local fertility spirits and appear ubiquitously in Khmer art (see Art section). Over time, elements of Buddhism were also syncretized. Jayavarman II’s cult of the god-king drew on Hindu theology, but later Angkorian kings like Jayavarman VII blended Mahayana Buddhist ideals with the earlier cult. Even under officially Hindu kings, Buddhist monks and monasteries were tolerated and patronized, and Hindu and Buddhist practices coexisted peacefully in the empire . By the 13th century, Theravada Buddhism spread among the populace, yet it absorbed the existing Hindu and animist framework rather than displacing it completely. For instance, villagers continued to venerate Hindu deities and local spirits at small shrines, while Buddhist pagodas were often built on or near former Hindu sacred sites, maintaining continuity of holy ground . The famous “River of a Thousand Lingas” at Phnom Kulen – where hundreds of Shiva lingams are carved into a riverbed to bless the waters – is a testament to how deeply Hindu worship was tied to the land . Long after the fall of Angkor, local people still revered these lingas and Hindu icons, showing the enduring devotion to Hindu symbols even as formal Hinduism waned .
Kingship and Political Systems: The Devarāja Cult
Hinduism’s influence on Khmer political ideology was profound, especially through the concept of the divine kingship. At Angkor’s height, the Khmer kings were seen as god-kings – earthly embodiments of Hindu deities who ruled by divine mandate. This notion was formalized by Jayavarman II’s institution of the Devarāja (Deva Raja, “Lord of the Gods” or “God-King”) cult in the 9th century . In this cult, the king was consecrated as a manifestation of Shiva (often identified with the term Śiva or sometimes Vishnu) and an owner of a sacred linga that housed his royal essence . During a mystical coronation ritual, presided over by a Brahmin high priest, the king’s soul was symbolically fused with the deity’s spirit in the linga . The linga – typically installed in a special mountain-temple (such as the pinnacle of Phnom Bakheng or Bakong temple) – acted as both the ritual heart of the kingdom and a palladium that guaranteed the prosperity and security of the realm . Safeguarding this sacred phallic idol was therefore a matter of state security; losing it could mean the loss of divine favor and political legitimacy .
Under this Hindu political theology, Khmer monarchs styled themselves as Chakravartin (universal rulers) and took on posthumous names identifying them with gods (e.g. Suryavarman II’s posthumous name Paramavishnuloka means “He who has gone to the realm of Vishnu”) . Royal inscriptions often describe kings as the “offspring of the gods” or liken their victories to those of Indra or Rama, thereby reinforcing that the king upheld dharma (cosmic order) in the realm . The construction of grand temples was itself a political act: each temple legitimized the king’s divine right to rule and commemorated his union with a deity . For example, Angkor Wat was not only a Vishnu temple but also intended as Suryavarman II’s mausoleum, conflating king and god in one sacred complex . Later, King Jayavarman VII, though a Buddhist, adopted the model by identifying himself with the Bodhisattva Avalokiteshvara, showing the lasting template of divinized kingship.
The Hindu influence also extended to Khmer law and administration. Khmer legal codes and court ceremonies drew on Indian Dharmashastra traditions and Sanskrit terminology. Positions like royal chaplains and astrologers were held by Brahmins, and Indian notions of caste were partially reflected in the stratification between Brahmin priests, Kshatriya-like warrior nobility, and commoners – albeit less rigidly than in India. Moreover, surrounding Southeast Asian kingdoms (the Thai, Cham, etc.) adopted elements of Khmer court culture; the Khmer in turn had borrowed the Indian concept of a sacred monarchy, and this became a standard in the region . In short, Hinduism provided the cosmological blueprint for governance: the king was the axis between heaven and earth (the Mount Meru of his realm), responsible for maintaining harmony as per Hindu cosmology. This legacy persisted even as Cambodia’s rulers later became Buddhist – the monarchy continued to be wrapped in sacred reverence, and coronation rites to this day include Brahmanical elements that echo the devarāja ritual of ancient Angkor .
Art and Architecture: Hindu Imagery in Stone
Hinduism’s mark on Khmer art and architecture is perhaps the most visible and celebrated aspect of its influence. The Khmer Empire’s architectural achievements – especially the temple-cities of Angkor – were fundamentally inspired by Indian temple forms and mythological symbolism. Khmer temple architecture evolved from Indian models (both North Indian nagara and South Indian dravidian styles) but developed a distinctive Khmer style over time . The concept of the temple as a representation of the Hindu universe was fully embraced: temples were laid out as mandalas with central towers symbolizing Mt. Meru, and their spatial plan aligned with cardinal directions and cosmic cycles . Angkor Wat, built in the 12th century, is the pinnacle of this design philosophy. It combines the temple-mountain form (a tiered pyramid evoking Meru) with concentric galleries and courtyards, all encircled by a vast moat representing the cosmic ocean . The central quincunx of towers at Angkor Wat corresponds to Meru’s five peaks, and the entire complex is oriented to the west, possibly for symbolic or funerary reasons . Such alignment and design reflect principles from Indian Vastu Shastra (sacred architecture texts), adapted to local conditions and ingenuity. Khmer builders, while following Indian cosmological blueprints, introduced local artistry, seen in their preference for certain materials (laterite, sandstone) and the development of unique structural solutions like corbelled arches.
Angkor Wat, the largest temple complex in the world, exemplifies Khmer architecture shaped by Hindu cosmology. Its five towers (visible above the tree line) represent Mount Meru, and extensive bas-relief galleries depict scenes from Hindu epics and mythology.
The sculptural art and decorative motifs of Cambodia are replete with Hindu imagery. Bas-reliefs on temple walls narrate Hindu epic stories and religious myths in elaborate detail. At Angkor Wat’s outer gallery, one finds an immense 50-meter panel of the “Churning of the Ocean of Milk” – a scene from Hindu mythology where gods (Devas) and demons (Asuras) churn the primordial ocean to obtain the nectar of immortality. This carving features 88 gods and 92 demons pulling the serpent Vāsuki wrapped around Mt. Mandara, with Vishnu orchestrating the event – an artistic tour de force that has captivated observers for centuries . Nearby panels show the Battle of Kurukshetra from the Mahabharata, Rama’s battle with Ravana (Battle of Lanka from the Ramayana), Krishna’s victory over Bana, and Hindu cosmological scenes of Heaven and Hell with the god Yama judging souls . These narratives in stone served both a didactic and a spiritual purpose: they linked the Khmer kings and their temples to the sacred history of Hinduism, reinforcing the sense that Angkor was a terrestrial replica of the divine realm . Even the smallest decorative details carried Hindu symbolism – kalas (monster faces) over gateways, lotus motifs symbolizing divine purity, and rampant garudas (the eagle mount of Vishnu) alternating with nagas on bridge balustrades, symbolizing the harmony of heaven and earth.
Khmer sculptors produced countless free-standing statues of Hindu deities, many of which rank among the masterpieces of Asian art. Iconic examples include graceful Shiva lingam-yoni altars, multi-armed Vishnu images (often shown holding a conch, discus, mace, and orb), serene Brahma figures with four faces (reflecting the Bayon style of the late 12th century), ferocious forms of Durga slaying the buffalo demon, and elephant-headed Ganesha figures invoked for auspicious beginnings. While modeled on Indian iconography, these statues feature distinctly Khmer stylistic features – such as idealized faces with soft, round contours, almond eyes and subtle smiles – giving the Hindu gods a Khmer visage . The devatas and apsaras carved in Angkor Wat’s walls, for instance, have local hairstyles, ornaments, and facial types, illustrating how Khmer art localized the depiction of celestial beings . These female figures, often interpreted as apsara dancers, are a signature motif of Angkorian art and number in the thousands at Angkor Wat . They likely represent both Hindu nymphs and deified royal dancers, bridging religion and royal court culture.
In sum, Hinduism gave Khmer art its central themes and icons – Rama and Sita, Shiva and Uma, Vishnu and Lakshmi, Indra on Airavata, etc. – and a cosmic framework that turned Cambodia’s cities into sacred landscapes. At the same time, Khmer artisans were not mere imitators; they assimilated and reinterpreted Indian art, creating a hybrid style that is unmistakably Khmer. The enduring beauty of temples like Angkor Wat, Bayon, Banteay Srei, and dozens of others stand as stone testaments to the creative synthesis of Indian spiritual vision with Khmer artistic genius.
Language and Literature: Sanskritic Heritage
The influence of Hinduism on Khmer language and literature is significant, beginning with the very script and vocabulary that Cambodians use. The Khmer writing system descends from the ancient Brahmi script of India, transmitted via the Pallava script of South India by the 6th–7th century . The earliest Khmer inscriptions (dating from the 7th century) are written in Sanskrit and Old Khmer using Pallava characters, and over time these evolved into the distinctive Khmer script in use today . This Indic script enabled the recording of royal edicts, religious texts, and literature. Notably, many Khmer place names and royal titles are derived from Sanskrit. The very name “Angkor” comes from nokor (city), which in turn comes from Sanskrit nagara (town) . Likewise, “Phnom” (hill) in names like Phnom Penh is related to the Sanskrit prasanna or bhumi, and the traditional name of Cambodia, Kambuja or Kampuchea, originates from Kambujadesha, a Sanskrit term found in old inscriptions .
Throughout the Angkor period, Khmer civilization was essentially bilingual at the elite level: Sanskrit was the language of scholarship, religion, and administration, while Old Khmer was the language of the people (and later of Buddhist texts). Thousands of inscriptions on temple stelae and pillars were composed in ornate Sanskrit verse praising Hindu deities and kings, demonstrating how thoroughly Khmer intellectual life was embedded in the Indosphere. At the same time, Sanskrit and its sister liturgical language Pali (from Buddhist influence) enriched Khmer with a vast reservoir of loanwords. Khmer absorbed Indic terms for religious concepts, royal ranks, astrology, arts, and more. For example, words like brah (from Brahma or brahman, meaning a priest), rāja (king), devī (goddess, which in Khmer became a term for queen), and many others became naturalized. The Khmer language today still contains a significant layer of Sanskrit-Pali vocabulary, especially in royal and religious registers . A modern Cambodian monk’s chant or a royal ceremony will feature phrases that are essentially Sanskrit or Pali, much as Latin permeates the liturgy of European languages . This linguistic legacy is a direct result of the Hindu (and later Buddhist) civilizational influence during the first millennium CE.
Khmer literature and performing arts likewise bear Hinduism’s stamp. As discussed in the Mythology section, the Reamker (Ramayana) is a cornerstone of Cambodian literature and has been adapted into a uniquely Khmer epic poem . The Reamker, along with other Indian-derived tales (such as Jataka Buddhist stories, many originally from Hindu folklore), provided content for Cambodia’s literary tradition. In the post-Angkorian period (16th–19th centuries), when Cambodia was officially Buddhist, scribes continued to copy and perform the Reamker and Mahabharata stories, and even composed new works inspired by them. One notable 17th-century Khmer poem, L’bok Ấngkor Wat (“The Poem of Angkor Wat”), describes the bas-reliefs of Angkor Wat and retells the Rama story depicted there – showing how Hindu epics were continually reinterpreted.
Traditional Khmer theater and dance are inseparable from Hindu narratives. The Royal Ballet of Cambodia (Khmer classical dance) has for centuries performed episodes from the Reamker and other Hindu myths as dance-dramas . Classical dances like the Robam Reamker (Ramayana dance) and Robam Tep Apsara (Apsara dance) directly draw on Hindu characters and symbolism: dancers costumed as Rama, Sita, Hanuman, or as celestial nymphs, enact stories of gods and heroes to the accompaniment of music and chants . Even in village folk theater (lakhon bassac, etc.), one finds local plays based on Samudra Manthan (the Churning of the Ocean) or Prahlad (a Vishnu devotee’s tale) woven into Cambodian folk idioms. Such performances kept Hindu legends alive in the popular consciousness well into the modern era, long after Hindu worship had faded. Indeed, Cambodia’s intangible heritage – from proverbs and idioms that reference the Ramayana, to the iconography of Cambodian dance (crowned dancers with hand gestures codified in Angkor’s reliefs) – reveals a deep strata of Hindu cultural memory that underpins national identity.
Social Customs and Lasting Cultural Impacts
Though the Khmer people embraced Theravada Buddhism from the 14th century onward, many social customs and traditions in Cambodia still reflect Hindu influence, attesting to a lasting cultural impact. Cambodian life-cycle ceremonies and state rituals often incorporate a dual religious approach: Brahminical rites alongside Buddhist rites . For example, at weddings or housewarmings, it is common to begin with a Vedic chant by Brahmin priests, invoking Hindu deities like Brahma or Shiva for blessings, before proceeding to Buddhist prayers by monks . In a Cambodian wedding, the couple reenacts the marriage of Preah Thong and Neang Neak – the groom symbolically following the bride while holding her sash – to honor the mythical first union of Khmer ancestors . During funerals, Brahmin priests may sprinkle holy water and offer rice balls (pinda) to guide the spirit of the deceased, after which Buddhist monks recite sutras . This seamless blending is a legacy of Cambodia’s “marriage” of Hindu and Buddhist practice; the presence of Brahmin officiants in ostensibly Buddhist ceremonies is like a living “wink to history,” reminding Cambodians of Angkor’s Hindu past .
Cambodia’s royal ceremonies in particular are steeped in Hindu traditions. The annual Royal Ploughing Ceremony (Bon Chroat Preah Nongkoal), held at the start of the rice-planting season, is led by royal Brahmins who ritually plough a sacred field and then interpret the eating behavior of oxen to predict the harvest – a practice with clear Vedic origins that was revived by King Norodom Sihamoni in recent years . The Khmer New Year festivities and Pchum Ben (ancestors’ festival) also feature Brahmin priests performing initial consecrations and fire offerings before the Buddhist observances begin . Even the coronation of Cambodian monarchs today requires the participation of hereditary Brahmin priests (known as Bakus), who chant Sanskrit mantras, anoint the king with sacred oils, and invoke the Hindu god Vishnu’s protection, much as was done for Angkorian kings centuries ago . These royal Brahmins are said to be descendants of the Angkorian priestly families . They serve as “cultural glue,” binding the modern Cambodian Buddhist state to its Hindu roots with every chant, flame, and blessed grain of rice” .
Beyond rituals, everyday Cambodian culture shows subtle echoes of Hinduism. Traditional dance dramas of the village (lkhaon) still recount tales of Ramakerti (Ramayana) or the Mahabharata to popular audiences. Artistic motifs like the apsara have been revived as national symbols – the image of an Angkorian apsara dancer is an icon of Cambodian identity, adorning everything from tourism brochures to currency. Many Cambodian names and honorifics are derived from Sanskrit (for instance, Indra, Devi, Vishnu appear in personal names). Cambodian classical music and shadow puppetry (sbek thom) use narratives of Hindu origin as well. Moreover, aspects of traditional law and social norms hark back to Hindu models, such as concepts of ritual purity, or the calendar system with its 7-day week named after planetary deities (e.g. Angaraj for Tuesday from Angaraka (Mars), etc.).
The modern Cambodian mindset retains respect for the ancient Hindu sites and stories as a proud heritage. Millions of Cambodians, though devout Buddhists, visit Angkor not just as tourists but as pilgrims, paying homage to the greatness of their ancestors’ religious devotion. Villagers near Angkor continue to light incense to Tevoda (deva) statues and offer flowers to images of Vishnu or Buddha interchangeably, reflecting a truly syncretic faith . The revival of interest in Angkor in the 21st century – aided by UNESCO and scholarly research – has prompted young Cambodians to learn Sanskrit chants and preserve the Brahmanical rituals that nearly vanished under past regimes . A striking example of renewed celebration of the Hindu legacy is the inauguration in 2022 of a giant statue of Preah Thong and Neang Neak in Sihanoukville, symbolizing the mythic foundation of Khmer culture .
In conclusion, Hinduism’s influence on Khmer culture has been pervasive and enduring. It provided the divine narratives, artistic inspirations, linguistic enrichment, and political-religious frameworks that undergirded the great Angkor civilization. Even after the decline of Hindu worship, the cultural DNA of Cambodia remained indelibly marked by its Hindu past – from the towering spires of Angkor Wat and the epic poetry of Reamker, to the ritual of a village wedding and the Sanskrit echoes in a royal coronation. The Khmer example illustrates how a civilization can adopt and localize a foreign religion so thoroughly that it becomes an integral part of its own identity. In Cambodia’s case, the legacy of Hinduism lives on as a cultural heritage, continually interpreted anew by each generation as they honor “the unique identity of Cambodia” forged from the fusion of Indian and Khmer traditions centuries ago .
